SPECIFICATION forming part of Letters Patent No. 709,67 3, datedSeptember 23, 1902.

Application filed April 24, 1.902.

1'0 aZZ whom it may concern:

Be it known that I, LEWIS WV. HEMP, of the city of St. Louis, State ofMissouri, have invented certain new and useful Improvements in Stoves,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming a part hereof.

Myinvention relates to heating-stoves; and it consists of the novelconstruction, combination, and arrangement of parts hereinafter shown,described, and claimed.

My object is to construct an improved heating-stove; and my inventionconsists of a suitable casing having a fuel-opening in the forward partof its top and having a chimneyopening in the rear part of its top andhaving draft-openings one on each side of the chimney-opening;draft-inlet dampers controlling said draft-openings; a fire-box mountedin said casing and held up from the bottom to form part of the hot-airspace, said fire-box being shortened at the rear to form a second partof the hot-air space communicating with the first hot-air space and withthe chimneyopening and said fire-box being shortened at the front toform a third part of the hot-air space communicating with the firsthot-air space and with the top of the fire-box; a wall extendingupwardly from the rear edge of the fire-box to the top of the casing infront of the chimney-opening, there being a damperopeningin said wall; adraft-directing damper in said damper-opening, and walls extendingbackwardly from the fire-box to the casin g to reduce the size of saidsecond hot-air space and forming cold-air passages, one on each side ofsaid second hot-air space, said coldair passages connecting thedraft-inlet openings with openings in the lower part of the fire-box,there being bottoms in said cold-air passages, so that when thedraft-directing damper is closed the air will pass through saiddraft-openings downwardly through said cold-air passages, upwardlythrough the firebox, downwardly through said third hot-airspace,backwardly under the fire-box through said first hot-air space,upwardly through said second hot-air space, and out through saidchimney-opening, and so that when the draft-directing damper is open theair will pass downwardly through said cold-air pas- Serial No. 104,493.(No model.)

sages,upwardly through the fire-box,and then through the damper-openingto the chimneyopening.

Figure 1 is a vertical central section of a stove embodying theprinciples of my invention. Fig. 2 is a top plan view, parts beingbroken away to illustrate their construction. Fig. 3 is a perspectiveshowing the walls extending backwardly from the fire-box to form thecold-air passages and bottoms in said passages, the upper parts beingbroken away to economize space.

Referring to the drawings in detail, myimproved heating-stove comprisesa suitable casing 4, mounted upon legs 5 and having the fuel-opening 6in the forward part of its top and having the chimney-opening 7 in therear part of its top and having the draft-inlet openings 8 and 9, one oneach side of the chimney-opening; draft-inlet dampers 10, controllingthe draft-openings; the firebox 11, mounted in the casing and held upfrom the bottom by means of the legs 12 to form part of the hot-airspace 13, said fire-box being shortened at the rear to form a secondpart of the hot-air space 14:, communicating with the first part of thehot-air space 13 and with thechimney-opening 7, and said fire-box beingshortened at the front to form the third part of the hot-air space 15,

communicating with the first part of the hot-air space and with the topof the firebox; the wall 16, extending upwardly from the rear edge ofthe fire-box to the top of the casing in front of the chimney-opening'7, said wall having the chimney-opening 17 the draft-directing damper18, mounted in said damper-opening; and the walls 19 and 20, extendingbackwardly from the fire-box to the casing to reduce the size of saidsecond hot-air space and form cold-air passages 21 and 22, one on eachside of said second hotair space, said cold-air passages connecting thedraft-inlet openings with the openings 23 in the lower rear part of thefire-box, there being bottoms 24: in said cold-air passages. The cover26 closes the fuel-opening 6, and the handle 27 serves as a means ofoperating the draft-directing damper 18.

When the draft-inlet dampers are opened and the draft-directing damperis closed, the air will pass through the openings 8 and 9,

throu gh the cold-air passages 19 and 20 into the lower part of thefire-box, upwardly through the fire-box,downwardly through the air-space15, backwardly under the fire-box through the air-space 13, upwardlythrough the air-space l4, and out through the chimney-opening 7. Thus itwill be seen that the hot air passes entirely around the fire asrequired to heat the front and bottom of the stove, as Well as the rearpart.

If the draft-directing damper 18 is opened, as it should be when thefire is about to be started, the air will pass downwardly through thecold-air passages 19 and 20 and upwardly through the fire-box, throughthe damperopening, and out through the chimney-opening.

Special attention is called to the fact that the cold-air passages areon each side of the hot-air passage leading to the chimney, so that thecold air passing into the firebox will be warmed by the hot air passingto the chimney.

I claim- A heating-stove comprising a suitable casing having afuel-opening in the forward part of its top, and having achimney-opening in the rear part of its top, and having draftopeningsone on each side of the chimneyopening; draft-inlet dampers controllingsaid draft-openings; a fire-box mounted in said casing and held up fromthe bottom to form part of the hot-air space, said fire-box beingshortened at the rear to form a second part of the hotair spacecommunicating with the first hot-air space and with the chimneyopening,and said fire box being shortened at the front to form a third part ofthe hot-air space communicating with the first hot-air space and withthe top of the firebox; a wall extending upwardly from the rear edge ofthe fire-box to the top of the casing in front of the chimney-opening,there being a damper-opening in said wall; a draftdirecting damper insaid damper-opening; and walls extending backwardly from the fire-box tothe casing to reduce the size of said second hot-air space, and formingcoldair passages one on each side of said second hot-air space, saidcold-air passages connecting the draft-inlet openings with openings inthe lower part of the fire-box, there being bottoms in said cold-airpassages; so that when the draft-directing damper is closed the air willpass through said draft-openings downwardly through said cold-airpassages, upwardly through the fire-box, downwardly through said thirdhot-air space, back wardly under the fire-box through said first hot-airspace, upwardly through said second hot-air space, and out through saidchimneyopening; andso that when the draft-directing damper is open theair will pass downwardly through said cold-air passages, upwardlythrough the fire-box, and then through the damper-opening to thechimney-opening, substantially as specified.

In testimony whereof I aifix my signature in presence of two witnesses.

LEWIS W. HEMP.
